This invention is designed to vary the speed adjustment of a governor with means maintaining a close regulation at each speer Features and details of the invention Will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follovvs liig. 1 shovvs a side elevation of a governor.

Fig. 2 a section on the line 2-2 in Fig, 1.

Fig. 3 a side elevation of an alternative construction.

Fig. A a perspective vienT of the adjusting device of the governor. v

1 marks the engine shaft, 2 a governor carrier on the shaft, 3 a swinging Weight arm, l a pin on Which the Weight arm is mounted, 5 a lined Weight on the Weight arm, 6 a swinging Weight carried by a pin 7 on -the Weight arm, 9 a stop for the release position, 10 a maximum stop, 11 an eccentric secured to the Weight arm, 12 a leaf spring pivotally connected at l2n on the swinging Weight, 13 a base on Which the spring is anchored, 111 a clamp for the spring, and 15 a bolt for ses curing the spring. These parts are of prior construction.

ln carrying out my invention I provide a spring n 1G. base 13 and secured by a clamp 16a and bolt 17. A shackle 18 is secured by a' pin 19 ony the free end of the spring and carries the pulleys 20. A cable21 is anchored on the carrier 2 at 22, passes around one of the pulleys 2O over pulleys 23 mountedon the swinging Weight V6, returned around a second pulley 2O on the shackle 18 and Wound on a spool 24. The spool 2A. is ,mounted on a shaft 2441, the shaft belng journaled in a bracket 24h. The bracket is mounted on the carrier. A gear 25 is iixed on the shaft 24 and meshes With a gear 26. The gear 26 is iiXed on a shaft 27. A crank 28 is mounted on the shaft 27. A pavvl 29 Works on Jthe gear 26 to lock the partsin position. i

1When the cable is fully loosened the counterspring 16 does not exert any influence on the governor, the governor operating en-. tirely under the action of the spring 12. When it is desired to 'reduce the centripetal element and consequently the normal speed of the governor tension is put on the counterspring l'by means of the cable 21, this being Wound on the spool 24 sufficiently to give the counterspring any tension desired,

The spring is mounted on the 1924. Serial No.:71-2,243.

the tension of the counterspring reducing the efiectiveness of the main spring to the extent ofthe strength of the counterspring at the I adjustment made. In this Way a very Wide range of adjustment may be accomplished and at the same time a close regulation at each speed.

ln the alternative construction a shackle 30 is mounted on the free end of the counterspring. A sleeve 31 is carried by the shackle. A screw 32 extends through the sleeve and is provided With a head 33. The screw extends through a trunion 311 carried by arms 35 on the swinging Weight. A ratchet lever 3o is mounted on the screw by means of which the screw may be operated to adjust the relation of the free ends of the spring and consequently the effect of the counterspring on the governor.

l/Vhat I claim as new' is z- 1. In an engine governor, the combination of a swinging governor weight; a governor spring resisting the outward movement of said Weight; a counterspring directly opposed to the governor spring for resisting the governor spring, said springs having their free ends adjacent and connected; and means for adjusting the effective strength of said springs.

2. ln an engine governor, the combination of a swinging governor Weight; a governor spring `formed of flat leaves resisting the out-Ward movement of said Weight; a counterspring formed of flat leaves directly opposed to the governor spring for varying the resistance of said governor spring, said springsV having their free ends adjacent and connected; and means for adjusting the effective strength of said springs.

3. In an engine governor, the combination of a swinging governor Weight; a governor spring formed of flat leaves resisting the outward movement of said Weight; a counterspring formed of flat leaves directly opposed to the governor spring for varying the resistance of said governor spring, said springs having their free ends adjacent and connected; and means for adjusting the en'ective strength of the counterspring.

4t. In an engine governor, the combination of a swinging governor Weight; a governor spring formed of dat leaves resisting the outward movement of said Weight; a coun terspring formed of fiat leaves directly opposed to the governor spring for varying the 10 Josed to the Governor s )rinor for ver 'i110' the D D D resistance of szld governor spring; un mi justing :means connecting the free ends; of said syringe eoirlprisng e Hexible member operatmg on pulleys between the free ends of said springs; and devices for adjusting 15 undloeking the flexible member.

n testimony whereotI l have hereunto set my hand.
